Window boxes are the perfect way to make dormers look extra special. Create lots of season-long interest with a mix of profuse bloomers, such as this verbena, and unusual foliage, such as flowering kale and sedge. That way you can enjoy the beautiful leaves and their distinct textures if the flowers take a break.

You can't beat coleus for gorgeously colored foliage. This mix of super-saturated leaf colors will give you a great view out -- and give your home wonderful curb appeal -- all summer long. Tip: Coleus also grows well indoors; take cuttings of your favorite varieties before the end of the season and treat them like houseplants so you can enjoy them all year long.

Create a "wow" look in your window boxes with double petunias. Their ruffled flowers create a lot more interest than their more traditional cousins. Enjoy their elegant blooms on the plant or snip a couple and float them in a glass of water for a wonderful little accent or summer centerpiece.

A big window needs a bold window box -- and here's a great example. This container has it all: tons of texture, depth, and dimension. It's a riot of color that'll help your home feel like it's worth a million bucks. And it's bold enough that it doesn't get overshadowed by the size of the window.

Take an all-white theme to the next level with silvery foliage. From silvery licorice vine to the artemisia shown here, silver foliage adds something special to your planting. Bonus: Light colors such as silver and white show up best at night, and seem to glow at dusk so you can enjoy them longer into the night.

Like a soft rain, delicate blue lobelia flows over the side of this window box. Many types of lobelia have a tendency to fade out during the hottest summer days, so pair them with another heat-loving blooming trailer such as cascading petunia or million bells (also called calibrachoa) to keep your display looking good all season long.

Take the idea of a window box and put it on your deck rails for a brilliant burst of color. For an outstanding all-put-together look, use the same plantings on your deck as you do beneath your windows. Your friends will love your creativity.

Here's another enchanting planting to decorate your deck or your home. Because pansy is a cool-season plant, you have the opportunity to give your window box a new look as the seasons change.

What could be better than reaching out to your window box and grabbing a handful of edible flowers, herbs, or vegetables for supper? Try edibles with ornamental appeal for two times the pleasure.

Petunias and geraniums are no-fail choices for hot, sunny spots -- so fill your window boxes with their colorful blooms and know you can enjoy their display of nonstop flowers all summer long. Tip: Pay attention to the variety; many newer petunias and geraniums bloom more and with less care than older selections.

An all-white wall may seem like it needs an explosion of color to dress it up, but you can create an equally impressive display by going with soft, subtle shades. Petunias and geraniums are the perfect choice for adding color either way -- let your personality be your guide.

Garden designers know the power of contrast. Whether you're contrasting colors, shapes, or sizes, make an eye-catching combo of opposites. Here, plant habits create the contrast. As a golden coleus reaches for the sky, trailing osteospermum and verbena grow with gravity.

If you love country style, you can't beat the simplicity of a rustic window box filled with a few lush plants. Here, for example, purple verbena and gold licorice plant make a striking contrast against the peeling red paint on the walls. Tip: Other ways to create the country look are to pick plants with a loose, open habit and use old-fashioned or recycled containers.

Be playful with window boxes and enjoy them even if you don't have a window. This weathered box made of planking goes vertical with a vintage window frame attached to the back.
